![]() The magnetic field is essentially uniform down the length of the coil when it is wound tighter. ![]() A loosely wound coil is illustrated below to show the interaction of the magnetic field. The magnetic field circling each loop of wire combines with the fields from the other loops to produce a concentrated field down the center of the coil. When a current carrying conductor is formed into a loop or several loops to form a coil, a magnetic field develops that flows through the center of the loop or coil along its longitudinal axis and circles back around the outside of the loop or coil. Describe what kind of magnetic field is produced by a current carrying coil.After reading this section you will be able to do the following:
